Detailed Description

A no-op logger implementation for fallback scenarios.

NullLogger provides a safe default when no logger has been registered. All logging operations are no-ops that return success without performing any actual logging. This prevents null pointer dereferences and allows code to function (silently) even when logging is not configured.

Note

Issue #177: Updated to support source_location-based logging.

Issue #217: Removed deprecated file/line/function API in v3.0.0.

Definition at line 52 of file global_logger_registry.h.
